Webb30 jan. 2024 · In the Reynolds number range just above transition, the skin friction coefficient is in good agreement with the experiment by Jones and the DNS by Tsukahara et al. . However \(C_\mathrm{f}\) is about 10% lower than the implicit relations suggested by Jones ( 1976 ), Dean ( 1978 ), Monty ( 2004 ), Zanoun et al. ( 2009 ) and Schultz and … WebbThe airflow characteristics were quantified using pressure distribution, skin friction coefficient, velocity profile, Reynolds number, Turbulent Reynolds Number, and Turbulent Kinetic Energy (TKE). Contour plots at different planes were used to visualise the airflow distribution as it passed through different cross-sectional areas of the airway. WebbReynolds numbers of 1 to 30 million per foot. Skin fric- tion predictions are compared with the semi-empirical theories. Estimations of solution convergence and errors are discussed. Different transformations of Reynolds number and skin friction are used for several compari- sons with the skin friction theories. COMPUTATIONAL PROCEDURE dm sarajevo ferhadija radno vrijeme
